Just got the pebble watch and saw it had a golf app, but the problem is I play disc golf. Is there any golf apps for the pebble that let you create your own courses with custom lengths? I saw the free caddie app, but as far as I can tell, I can only download ball golf courses.

The way free caddie works is that it allows users to create there own courses. I mapped out my local course, and only needed to enter the name for it to locate. Just locate a course around the disc golf course and then find it (it's a google maps thing). Then just map it out. The only thing is that it asks for front center and middle of greens so I guess just did regard the front and back in your case.
